2. Built in l853 and then largely rebuilt and enlarged, especially to west in l903 following a major fire the previous year. The builder was John Jones and it cost £5,500.

The building is cinstructed of coursed rubble with a high plinth, and hipped slate roofs with tiled cresting and boarded eaves. The main part of the composition is the advanced 3-bay front dated l853 with freestone classical detail. This includes a pediment with a large blind roundel over a plain entablature with lettering and the date. Each bay is flanked by paired Tuscan pilasters over plinth. The front elevation is lit by horned sash windows - 20-pane to centre, otherwise l6-pane, and there are cenrally placed panelled double doors with some glazing bars removed to the overlight.

To the left is a 2-storey, 3-bay, 1903 period range, the roof of which steps up slightly at corner. the windows have cambered voussoir heads to horned l6-pane sashes and there is a 6-panel door to the right with an overlight; all with tall keystones.
The enlargements to the right are attached and consist of a single storey, L-shaped market building, the tall roof rising to a raised clerestory, the end of which has an open pediment containing a round arched louvred ventilator. The roof is part glazed below the clerestory.

The long facade to Market Street has a central datestone, and tall and broad semi-circular arched openings to left and right with tall keystones. There are modern glazed double doors with tall small pane overlights. The long 6-bay, west elevation is of rubble stone, with a blocked doorway and a tall, round arched, doorway at the far end.

At the east side the front wall projects to carry the iron gate pier at the yard entrance. Behind that the side elevation has stock brick dressings and horned sashes. The main market building turns east (the short arm of the 'L') and has 2-storey elevation to the yard. This is a broken gable with a raised clerestory and a louvered roundel over a central thermal window with small pane glazing. Entrances to left and right are as on the Market Street front, although the right hand doorway has been mostly bricked up. The main north/south range continues a short way beyond this arm and the two clerestories are not linked.

Altered interior with false ceiling.
